I'm one of the scant few old enough to remember life before cable.
Once upon a time, before 1977, there were three networks. CBS, NBC, ABC, and PBS. Then in 1987 came Fox. That was IT! So you had to schedule your activities around your favorite shoes. And if you missed a show, you had to wait all week to see it again.
With cable, not only was reception a million times better, but we got HBO and a few Philly channels to add to our New York channels. Great Deal.
Things exploded in the 80s with MTV and Nick out of New York, and USA, TNT, CNN, and TBS out of Atlanta. But over the years more channels got added. Many started out promising having retro lineups like TVLand, Antenna, Noggin, Sprout, MeTV, etc. But after a few years and their contracts for airing older shows, they thought it would be cheaper to produce their own shows. Easier to air your own crap than license back catalogues and pay residual fees on them. That's what sank TBS.
TV is expensive business. It costs a small fortune to air a decades-old show, and ultimately either the advertiser or the viewer ends up paying for it. Money talks.
